Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Unger figures that Altgens held his camera tilted at an angle when he snapped the picture. Hmmm. That's weird. Why would Altgens do that? Most of us go our whole lives taking pictures in which we hold the camera level. It's only natural because we are used to looking at the world through level eyes. Of course, you can tilt your head, and hence your eyes, but usually you don't. I don't think I have ever taken a picture with a tilted camera. I've turned it 90 degrees a lot of times. But, it's been one or the other. Either, I've held it horizontal or I've held it vertical but never anything in-between. And, I think that's true of most people. 

And then Unger gives the example of some tilt in Wiegman, but that was a movie camera, and he was panning, and the result was a film. With Altgens, we are talking about a still picture. Way different! Apples and oranges.  Forget it, Unger. No basket.  

Presumably, Unger corrected for Altgens' tilt by tilting the image the other way to compensate. But, I don't think you tilted it far enough, Unger, because the tower still looks a little crooked to me. So, try it again. See if you can get it really straight.

But, maybe you shouldn't bother because Altgens talked at length about the moment he took the picture, and he even demonstrated it.

  
That looks like a pretty standard camera hold to me. I don't see that he is suggesting there that he held his camera at an angle.
